Important safety instructions for using
child safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of everybody
in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly::::>
page 227.
- Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
retractor on the safety belt to prevent the child safety seat
from moving ::::>
page 232.
-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety seat
to the front passenger seat, make sure that it is not so
tight that it causes the weight-sensing mat to measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size . ..,

in. WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death.
• All vehicle occupants and especially children must always be
restrained properly whenever riding in a vehicle .
- An unrestrained or improperly restrained child can be injured or killed by being thrown against the inside of the
vehicle or by being ejected from it during a sudden maneuver or impact.
- An unrestrained or improperly restrained child is at much greater risk of injury or death by being struck by an inflating
airbag.
• Commercially available child safety seats are required to
comply with U.S. Federal Motor Vehicle Safety Standard (FMVSS)
213 (in Canada CMVSS 213).
- When buying a child restraint, select one that fits your child and the vehicle.
- Only use child restraint systems that fully contact the flat portion of the seat cushion. The child restraint must not tip or
lean to either side. Audi does not recommend using child
safety seats that rest on legs or tube-like frames . They do not
provide adequate contact with the seat .
- Always heed all legal requirements pertaining to the instal­
lation and use of child safety seats and carefully follow the instructions provided by the manufacturer of the seat you are
using.
• Never allow children under 57 inches (1.5 meters) to wear a
normal safety belt . They must always be restrained by a proper
child restraint system. Otherwise, they could sustain injuries to
the abdomen and neck areas during sudden braking maneuvers or accidents.
• Never let more than one child occupy a child safety seat.
& WARNING (co ntinued )
• Never let babies or older children ride in a vehicle while sitting
on the lap of another passenger .
- Holding a child in your arms is never a substitute for a child
restraint system.
- The strongest person could not hold the child with the forces
that exist in an accident. The child will strike the interior of the
vehicle and can also be struck by the passenger.
- The child and the passenger can also injure each other in an
accident .
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat. A child will be seriously injured and can be killed when the passenger airbag inflates -even with an
Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, door or roof.
• Always install rear-facing child safety seats or infant carriers
on the rear seat.
• Forward-facing child safety seats installed on the front
passenger 's seat can interfere with the airbag when it inflates and
cause serious injury to the child . Always install forward-facing
child safety seats on the rear seat.
• If exceptional circumstances require the use of a forward·
facing child restraint on the front passenger's seat , the child's
safety and well-being require that the following special precau­
tions be taken:
- Make sure the forward-facing seat has been designed and certified by its manufacturer for use on a front seat with a
passenger front and side airbag .
- Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier.

vehicle safety belts without a suitable ch ild restraint.
Children up to abou t 40 lb s ( 18 kg) are bes t pro tec ted in child safety
seats des igned for the ir age and weight. Experts say that the ske letal

& WARNING
Not using a booster seat, using the booster seat improperly, incor­
rectly installing a booster seat or using the vehicle safety belt
improperly increases the risk of serious personal injury and death
in a collision or other emergency situation . To help reduce the risk
of serious personal injury and/or death:
• Always make sure to position the shoulder portion of the three­
point belt over the middle of child's shoulder.
• Never let the shoulder portion of the belt rest against or across
the neck , face , chin , or thro at of the child.
• Always make sure the lap belt portion of the three-po int belt is
worn snug and passes as low as possible across the child's pelvi s.
Never let the belt pass over the soft abdomen.
• Failure to properly route safety belts over a child 's body will
cause severe injuries in an accident or other emergency situation
~ page 190 .
• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag inflates.

& WA RNING (conti nued)
• Never let a child stand or kneel on an y seat, for example the
front seat.
• Never let a child ride in the cargo area of your vehicle.
• Alwa ys remember that a child leaning forward , sitting s ide·
ways or out of po sition in an y way during an accident can be struck
by a deploying airbag. Th is will result in serious personal injury or
death.
• If you must install a booster seat on the front passenger seat
because of e xceptional circumstance s the PASSENGER AIR BAG
OFF light must come on and stay on, whenever the ignit ion is
switched on.
• If the PASSENGER AIR BAG OFF light does not come on and
s tay on, perform the checks described =>
page 211, "Monitoring
the Advanced Airbag System ".
• Take the child re straint off the front pa ssenger seat and install
it prope rly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever the ignition i s swit ched

• Always make sure that the safety belt retractor is locked when
i nstalling a child safety seat . An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.
• Always buckle the child safety seat firmly in place even if a
child is not s itting in it. A loose child safety seat can fly around
during a sudden stop or in a collision.
• If the back rest is not securely latched , the child and the child
restraint will be thrown forward together with the backre st and ._

& WARNING (continued)
• A child in a rearward-facing child safety seat installed on the
front passenger seat will be seriously injured and can be killed if
the front airbag inflates -even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy the Advanced Airbag when it must be suppressed causing serious
or even fatal injury to the child.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install the rearward-facing child safety seat
in a rear seating position and have the airbag system inspected by
your authorized Audi dealer. •
Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint in your vehicle. To acti­
vate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat. -
Slowly pull the belt
all the way out.
- Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down with your full weight to
get the safety belt really tight.
- Insert the belt tongue into the buckle for that seating
position.
- Guide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
- You should hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pulling on the belt. You should no longer be able to pull
the belt out of the retractor. The convertible locking
retractor is now activated.
- Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
- Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot move forward
or sideways more than one inch (2.5 cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a crash.

Notice about data recorded by
vehicle control modu Les
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event. EDR's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped with
a number of e lectronic control modules for various vehicle systems
such as, for example, eng ine function, emission control, as well as for
the airbags and safety belts.
These electronic control modules also record vehicle-related data
during normal vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally recorded over a very limited period of time and stored when a
system fault or other condition is sensed by a control unit. Some of
the data then stored may relate to vehicle speed, direction, braking
as well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment .•
Electronic Stabilization Program
(ESP}
Ce-ieral lnforrrc:t~on
The ESP improves the vehicle stability.
Fig. 213 ESP button
Fig. 214 Center
console with ESP
switch
ESP is designed to he lp you maintain vehicle control in situations
where the car approaches the limits of "grip", especially when accel­
erating and cornering. ESP reduces the risk of skidding and improves
stability under all road conditions.

Intelligent technology
--------------------------------------------------' "---.L==--
The system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integ rated in the elec­
tronic stabilization program . In addition to the data provided by
these functions, the ESP control unit requires additional measure­
ment data provided by high performance sensors . The rotational
speed of the vehicle about its vertical axis, vehicle acceleration in the
fore-and-aft and lateral directions, the brake pressure, and the
steering angle are all measured .
Th e direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is con tinually
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the problem.
The vehicle is then stabilized by the forces acting on the whee l during
brak ing.
If the vehicle is oversteering (the vehicle turns too sharply
and the rear wheels slide toward the outside of a curve), the brakes
are mainly applied on the wheel that is on the outside of the curve. In
the case of a vehicle that is
understeering (the vehicle does not turn
sharply enough and pushes out of a curve), the brakes are applied as
needed on the wheel that is on the inside of the curve or additionally
on the other wheels. An acoustic signal indicates when ESP brake
application cuts in=> &.
The system operates across the entire speed range in combination
with the ABS system =>
page 245. If the Anti- Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
w ill perform a self-test. As soon as the test is comp leted, the system
is in normal operating mode.
Controls and equip­
ment Safety first Vehicle operation
You can activate a
deactivated ESP or deactivated ESP/ ASR if required
by pressing the =>
page 240, fig. 214 => page 240, fig. 213 button.
When they are activated, the message
ESP/ ASR on appears briefly
in the display.
Deactivating
The ESP should normally be activated all the time. If necessary, you
can deactivate Anti-Slip Regulation (ASR) or the Electron ic Stabiliza ­
tion Program (ESP) by press ing the button =>
page 240, fig. 214 .
• Deactivating ASR: Tap the button . In certain exceptional s itua­
t ions (e.g. driving with tire chains), the Anti-Slip Regu lation (ASR) can
be deact ivated =>
page 242. The message ASR off appears in the
display as we ll.
• Deactivating ESP/ASR Press the button for more than 3 seconds .
With the ESP/ASR deactivated, the ESP check light comes on, see
=>
page 14. The message ESP switched off appea rs in the display as
well.
& WARNING
The Electronic Stabilization Program is nevertheless subject to the
laws of physics. It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and
traffic conditions . Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks.

Intelligent t echnology
---------------------------------------
Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors=>
page 245. If a not iceab le
slip is detected at the wheels (e.g. on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
Electronic limited slip differential
In vehicles w ith front wheel drive *, an e lectron ic lim ited slip d ifferen­
tial engages when driving on curves . The brakes are applied spec ifi­
cally to the front wheel that is on the inside of the curve. T his m ini­
m izes sliding on the front wheels and enables precise and neutral dr
iv ing t hrouge curves. The electronic lim ited slip differentia l does
no t engage whe n driving in we t cond it io ns or snow.
& WARNING
• Wh en acc elerating on slipp ery s urface s, such a s on ice or snow,
always be careful when depre ssing the accele rator pedal. Even
with the EDL and the electroni c limited slip differential working,
the dr ive wh eels can spin and reduce you r ability to control your
c ar . -Ri sk of cra sh!
• The increased safet y afforded b y EDL and the electronic l imited
slip differ ential d oes not mean th at you can take safety risks .
Alw ay s adapt your d riving st yle to the road c onditions and traffi c
si tuation.
[ i ] Tips
If a fa ult occurs in the ABS, the EDL is also not funct ioning. This is
ind icated by the ABS warn ing light=>
page 16 . •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is a ccelerating.
General notes
T he Anti-Slip Regu lation System (ASR) is in tegrated in the electronic
stabilization program (ESP) . When the veh icle starts up and acceler­
a tes, the wheels are preven ted from sp inning by adjust ing the engine
power to match the amount of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervent ion.
With the a id o f the ABS sensors=>
page 245, ASR moni tors the speed
of the driven wheels. If the wheels start to spin, engine torque is
reduced automatically unti l the tires find enough grip to lock onto
the road s urface. The system is active across the entire speed range . .,
